Gas-liquid reactions form the basis of our everyday lives, yet they still suffer poor reaction efficiency and are difficult to monitor in situ, especially at ambient conditions. Now, an inert gas-liquid reaction between aniline and CO is driven at 1 atm and 298 K by selectively concentrating these immiscible reactants at the interface between metal-organic framework and solid nanoparticles (solid@MOF). Real-time reaction SERS monitoring and simulations affirm the formation of phenylcarbamic acid, which was previously undetectable because they are unstable for post-reaction treatments. The solid@MOF ensemble gives rise to a more than 28-fold improvement to reaction efficiency as compared to ZIF-only and solid-only platforms, emphasizing that the interfacial nanocavities in solid@MOF are the key to enhance the gas-liquid reaction. Our strategy can be integrated with other functional materials, thus opening up new opportunities for ambient-operated gas-liquid applications.

Sodium carbonate is an abundant, low-cost, and low-hazard raw material widely used as a food additive and CO absorbent in the food industry. However, its application in food packaging is limited because it is used in solid form, either in sachets or as a compounding ingredient in plastics. Solid sodium carbonate requires an external moisture supply for CO absorption, with its performance dependent on moisture availability.

Developing an exceptional reaction medium with high promotion efficiency, desirable biodegradability and good recyclability is necessary for hydrate-based methane storage. In this work, a kind of eco-friendly hydrogel, polyvinyl alcohol-co-acrylic acid (PVA-co-PAA), was utilized to absorb dilute sodium p-styrenesulfonate (SS) solution, for constructing a hybrid reaction medium for methane hydrate formation. Hydrogels or dilute SS solutions (1-4 mmol L) had weak or even no promoting effects on hydrate formation kinetics, while the combination of them could synergistically promote methane hydrate formation.

Copper-based catalysts demonstrate distinctive multicarbon product activity in the CO electroreduction reaction (CORR); however, their low selectivity presents significant challenges for practical applications. Herein, we have developed a multilevel porous spherical CuO structure, wherein the mesopores are enriched with catalytic active sites and effectively stabilize Cu, while the macropores facilitate the formation of a "gas-liquid-solid" three-phase interface, thereby creating a microenvironment with an increasing water concentration gradient from the interior to the exterior. Potential-driven phase engineering and protonation synergistically optimize the reaction pathway, facilitating a switch between CO and CH.

Analysing monosaccharide composition is an essential step in deciphering polysaccharide structures. However, it presents significant challenges due to the pronounced hydrophilicity and the vast array of monosaccharide isomers. Gas/liquid chromatography, coupled with an aldononitrile acetate derivatisation, has been widely used for monosaccharide composition analysis.
